Background: SARS-CoV-2 can enter the environment from the feces of COVID-19 patients and virus carriers through untreated sewage. The virus has shown the ability to adapt to a wide range of hosts, so the question of the possible involvement of aquafauna and animals of coastal ecosystems in maintaining its circulation remains open.
Methods: the aim of this work was to study the tropism of SARS-CoV-2 for cells of freshwater fish and reptiles, including those associated with aquatic and coastal ecosystems, and the effect of ambient temperature on this process.
Article Synopsis
- A retrospective study analyzed 13,699 samples in the Novosibirsk region from April to May 2020, finding a 6.49% positivity rate for SARS-CoV-2 among those tested.
- Of the positives, 42% were asymptomatic, and two cases had no known contact with confirmed COVID-19 patients.
- The analysis revealed the highest positivity in those aged 80+, identified three phylogenetic lineages (B.1, B.1.1, B.1.1.129), and noted mutations in the Spike protein among the sequenced isolates.
